GitHub Followers Manager

A powerful Go-based command-line tool to manage your GitHub following relationships. Follow users who follow a specific user but don't follow you, or unfollow users who don't follow you back.

✨ Features

• 🔍 Follow Management: Follow followers of a specific user who don't follow you back
• 🗑️ Unfollow Cleanup: Unfollow users who don't follow you back
• ⚡ Efficient Processing: Handle large numbers of followers/following with pagination
• 🛡️ Safe Execution: Interactive confirmation before bulk operations
• 🚀 Concurrent Processing: Configurable worker pool for fast execution
• 🔐 Secure Authentication: OAuth2 token-based GitHub API authentication
• ⚙️ Flexible Configuration: Environment variables and command-line flags
• ⏱️ Rate Limiting: Configurable delays to respect GitHub API limits

🚀 Installation

Prerequisites

• Go 1.24 or higher
• A GitHub account
• A GitHub Personal Access Token with the user:follow scope

Option 1: Build from source

1. Clone the repository: bash git clone https://github.com/dbunt1tled/github-unfollow.git cd github-unfollow

2. Install dependencies: bash go mod download

3. Build the application: bash go build -o github-followers ./cmd/main.go

Option 2: Install via Go

go install github.com/dbunt1tled/github-unfollow@latest

⚙️ Configuration

GitHub Personal Access Token

1. Go to GitHub Settings → Developer settings → Personal access tokens → Tokens (classic)
2. Generate a new token with the user:follow scope
3. Copy the token for configuration

Environment Variables

Create a .env file in the project root or set environment variables:

# Required
GITHUB_USERNAME=your_github_username
GITHUB_TOKEN=your_github_personal_access_token

# Optional (with defaults)
WORKER_COUNT=1      # Number of concurrent workers (default: 1)
QUEUE_SIZE=3        # Size of the worker queue (default: 3)
TIME_DELAY_MS=2000  # Delay between API calls in milliseconds (default: 2000)

Note: You can copy .env.example to .env and fill in your credentials.

🚦 Usage

The tool provides two main commands: follow and unfollow.

Follow Command

Follow followers of a specific user who don't already follow you:

# Basic usage - follow followers of 'username' who don't follow you
./github-followers follow username

# Skip confirmation prompt
./github-followers follow username --force
./github-followers follow username -f

Unfollow Command

Unfollow users who don't follow you back:

# Show users who don't follow you back (dry run)
./github-followers unfollow

# Actually unfollow users who don't follow you back without confirm
./github-followers unfollow --f
./github-followers unfollow --force

Unfollow Command

Unfollow users who don't follow you back:

# Basic usage - unfollow users who don't follow you back
./github-unfollow unfollow

# Skip confirmation prompt
./github-unfollow unfollow --force
./github-unfollow unfollow -f

Example workflow: 1. Tool fetches your followers list 2. Tool fetches your following list 3. Identifies users you follow who don't follow you back 4. Shows the list and asks for confirmation (unless --force is used) 5. Unfollows the users concurrently with rate limiting

Command-Line Flags

Both commands support the following flags:

• --force, -f: Skip interactive confirmation prompt (use with caution)
• --help, -h: Show help information

Help Command

# Show general help
./github-unfollow --help

# Show help for specific commands
./github-unfollow follow --help
./github-unfollow unfollow --help

Configuration Options

Worker Pool Settings

• WORKER_COUNT: Number of concurrent workers for API calls (default: 1)
• Higher values = faster execution but more API rate limit pressure

• Recommended: 1-5 for most use cases

• QUEUE_SIZE: Size of the task queue (default: 3)

• Buffer size for pending tasks

• Should be >= WORKER_COUNT

• TIME_DELAY_MS: Delay between API calls in milliseconds (default: 2000)

• Helps avoid GitHub API rate limits
• Lower values = faster execution but higher risk of rate limiting
• Recommended: 1000-3000ms

Example Configurations

Conservative (safe for large operations):

WORKER_COUNT=1
QUEUE_SIZE=3
TIME_DELAY_MS=3000

Balanced:

WORKER_COUNT=2
QUEUE_SIZE=3
TIME_DELAY_MS=2000

Examples

Using environment variables

# Set token and username via environment
export GITHUB_USERNAME="myusername"
export GITHUB_TOKEN="ghp_xxxxxxxxxxxxxxxxxxxx"
export WORKER_COUNT=2
export TIME_DELAY_MS=1500

./github-unfollow unfollow

Architecture

The project is organized into the following components:

• main.go: Application entry point
• cmd/: Cobra CLI commands
• root.go: Root command setup
• follow.go: Follow command implementation
• unfollow.go: Unfollow command implementation
• internal/: Internal packages
• config/: Configuration management with Viper
• git_hub_manager/: GitHub API client wrapper
• worker/: Worker pool for concurrent processing
• helper/: Utility functions

Security

• Your GitHub token is only used to authenticate with the GitHub API
• The token requires only the user:follow scope - no access to repositories or other data
• Tokens are loaded from environment variables, never hardcoded
• Never share your .env file or commit it to version control
• The .env file is included in .gitignore by default

Rate Limiting

GitHub API has rate limits: - 5,000 requests per hour for authenticated requests - Each follow/unfollow operation uses 1 API call - The tool includes built-in delays (configurable via TIME_DELAY_MS) - Use conservative settings for large operations

Troubleshooting

Common Issues

"Authentication failed" error: - Verify your GITHUB_TOKEN is correct and has user:follow scope - Check that the token hasn't expired

"Rate limit exceeded" error: - Increase TIME_DELAY_MS value - Reduce WORKER_COUNT - Wait for the rate limit to reset (1 hour)

"User not found" error: - Verify the username exists and is public - Some users may have restricted follower lists
